How To Test Cases For Login Page

How To Articles

Testing is a crucial step in the development process of any software application. When it comes to a login page, thorough testing is particularly important to ensure the security and functionality of the system. In this article, I will be sharing my personal insights and experiences on how to effectively test cases for a login page.

Understanding the Login Functionality

Before diving into testing, it is essential to have a clear understanding of the login functionality. The login page is the gateway to the application and plays a vital role in verifying the identity of users. It typically consists of input fields for username and password, along with a “Login” button.

In addition to the basic functionality, a login page may incorporate additional features such as password recovery, social media login options, or captcha verification. It is important to consider these factors while testing to ensure that all functionalities are working smoothly.

Creating Test Cases

When creating test cases for a login page, it is crucial to cover all possible scenarios to ensure comprehensive testing. Here are some test cases that I typically include:

  1. Valid Credentials: Test the login functionality using valid credentials. Verify that the user is successfully authenticated and redirected to the intended page.
  2. Invalid Credentials: Test the login functionality using invalid credentials. Ensure that appropriate error messages are displayed, and the user is not granted access.
  3. Password Recovery: Test the password recovery functionality to ensure that users can reset their passwords securely. Verify that a password reset link or OTP is sent to the user’s registered email address.
  4. Remember Me: If the login page has a “Remember Me” option, test its functionality to ensure that the user remains logged in even after closing and reopening the application.
  5. Account Lockout: Test the account lockout feature by entering incorrect passwords multiple times. Verify that the user’s account is locked after a specified number of failed login attempts.

Security Testing

Security is a critical aspect of a login page. Here are some security-focused test cases that I recommend:

  1. SQL Injection: Test for SQL injection vulnerabilities by entering malicious SQL statements in the input fields. Ensure that the system handles such inputs securely and does not execute the injected code.
  2. XSS Attacks: Test for cross-site scripting (XSS) vulnerabilities by inserting malicious scripts in the input fields. Verify that the system sanitizes user inputs and prevents the execution of these scripts.
  3. Password Encryption: Test the encryption of passwords to ensure that they are stored securely in the database. Verify that the passwords are hashed or encrypted using industry-standard algorithms.
  4. Session Management: Test the session management functionality to ensure that sessions are properly handled, and user sessions expire after a certain period of inactivity.


Testing the login page is a critical step in ensuring the security and functionality of an application. By creating comprehensive test cases and focusing on both functional and security aspects, you can identify and resolve any issues before they impact the user experience. Remember to document your test results and collaborate with the development team to ensure a seamless login experience for users.
